Check Digit Verification of cas no

The CAS Registry Mumber 155814-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,1 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 155814-63:
(8*1)+(7*5)+(6*5)+(5*8)+(4*1)+(3*4)+(2*6)+(1*3)=144
144 % 10 = 4
So 155814-63-4 is a valid CAS Registry Number.

Dispiroketals in Synthesis (Part 6): Highly Stereoselective Alkylation of Dispiroketal Protected Lactate and Glycolate Enolates

Downham, Robert,Kim, Kun Soo,Ley, Steven V.,Woods, Martin

, p. 769 - 772 (2007/10/02)

Protected lactic acid enolates have been alkylated with a range of electrophiles to give the substituted adducts with moderate to excellent stereoselectivity.A chiral protected glycolic acid adduct has also been doubly alkylated with high stereoselectivit
