286967-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 286967-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,6,9,6 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 286967-31:
(8*2)+(7*8)+(6*6)+(5*9)+(4*6)+(3*7)+(2*3)+(1*1)=205
205 % 10 = 5
So 286967-31-5 is a valid CAS Registry Number.

, p. 741 - 744 (1994)
The diastereoselectivity of nucleophilic adition to β-chiral acylsilanes is examined, and our method is applied to the stereoselective synthesis of calcitriol lactone, a major metabolite of vitamin D3.
