Check Digit Verification of cas no
The CAS Registry Mumber 135628-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,2 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135628-89:
(8*1)+(7*3)+(6*5)+(5*6)+(4*2)+(3*8)+(2*8)+(1*9)=146
146 % 10 = 6
So 135628-89-6 is a valid CAS Registry Number.

, p. 833 - 839 (1991)
A highly efficient resolution of (±)-1-octyn-3-ol through recrystallization of the diastereomeric esters has been achieved by using N-(p-toluenesulfonyl)-(S)-phenylalanyl chloride as resolving reagent. The method provides a facile and economical entry to
