Check Digit Verification of cas no

The CAS Registry Mumber 133210-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,1 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133210-27:
(8*1)+(7*3)+(6*3)+(5*2)+(4*1)+(3*0)+(2*2)+(1*7)=72
72 % 10 = 2
So 133210-27-2 is a valid CAS Registry Number.

Evidence for synclinal transition state in the reactions of aromatic aldehydes with α-(alkoxy)allylstannanes

Gung, Benjamin W.,Smith, Daniel T.,Wolf, Mark A.

, p. 5455 - 5466 (2007/10/02)

Unlike aliphatic aldehydes, aromatic aldehydes produce greater than 95% of syn-(Z) enol ether when treated with α-(alkoxy)allylstannanes in the presence of BF3·Et2O. However, in the presence of TiCl4, the reaction of p-chloro-o-methoxybenzaldehyde with α-(alkoxy)crotylstannane produced predominantly the syn-(E) isomer.
