Check Digit Verification of cas no

The CAS Registry Mumber 1378359-97-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,3,5 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1378359-97:
(9*1)+(8*3)+(7*7)+(6*8)+(5*3)+(4*5)+(3*9)+(2*9)+(1*7)=217
217 % 10 = 7
So 1378359-97-7 is a valid CAS Registry Number.

Facile synthesis of substituted isoquinolines

Chang, Meng-Yang,Wu, Ming-Hao,Lee, Nein-Chia,Lee, Ming-Fang

, p. 2125 - 2128 (2012)

A facile three-step protocol toward methoxy isoquinolines 7 starting with substituted 2-allylbenzaldehydes 9 was described. The overall synthetic process of skeleton 7 was carried out using the Grignard addition, PCC-oxidation, and one-pot oxidative cleavage of the olefinic group of skeleton 9 with OsO 4-NaIO4 followed by the condensation of the resulting 1,5-dicarbonyl compounds with NH4OAc. Skeleton 9 was prepared in high yield via the known Claisen rearrangement of skeleton 8 and O-methylation. Papaverine 2 is also synthesized via the simple three-step synthetic protocol.
