Check Digit Verification of cas no

The CAS Registry Mumber 77850-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,5 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77850-74:
(7*7)+(6*7)+(5*8)+(4*5)+(3*0)+(2*7)+(1*4)=169
169 % 10 = 9
So 77850-74-9 is a valid CAS Registry Number.

Synthesis of β-and β,β-substituted Morita-Baylis-Hillman adducts using a two-step protocol

MaGee, David I.,Ratshonka, Same,McConaghy, Jessica,Hood, Maggie

experimental part, p. 450 - 463 (2012/06/16)

The synthesis of a large number of β-and β,β-substituted keto esters was successful by the use of the Knoevenagel condensation reaction. The stereoselectivity of these reactions was improved by alteration of various substituent groups. Although there were
