Check Digit Verification of cas no

The CAS Registry Mumber 1379776-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,9,7,7 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1379776-89:
(9*1)+(8*3)+(7*7)+(6*9)+(5*7)+(4*7)+(3*6)+(2*8)+(1*9)=242
242 % 10 = 2
So 1379776-89-2 is a valid CAS Registry Number.

Paragraph 0081; 0085, (2017/01/02)

PROBLEM TO BE SOLVED: To provide a method for producing an α-pyranoside thiocarbonyl ester compound, in which the hydroxyl group at position 2 is selectively protected. SOLUTION: An α-pyranoside compound represented by general formula (I) or general

Organotin-catalyzed highly regioselective thiocarbonylation of nonprotected carbohydrates and synthesis of deoxy carbohydrates in a minimum number of steps

supporting information; experimental part, p. 4850 - 4853 (2012/05/20)

Nonprotected carbohydrates: The catalytic regioselective thiocarbonylation of carbohydrates by using organotin dichloride under mild conditions was demonstrated. The reaction afforded various deoxy saccharides in high yields and excellent regioselectivity in a minimum number of steps. The regioselectivity of the thiocarbonylation is attributed to the intrinsic character of the carbohydrates based on the stereorelationship of their hydroxy groups (see scheme). Copyright
