Check Digit Verification of cas no

The CAS Registry Mumber 1227718-79-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,7,1 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1227718-79:
(9*1)+(8*2)+(7*2)+(6*7)+(5*7)+(4*1)+(3*8)+(2*7)+(1*9)=167
167 % 10 = 7
So 1227718-79-7 is a valid CAS Registry Number.

Highly Z-selective synthesis of a,b-unsaturated nitriles using the Horner-Wadsworth-Emmons reaction

Ando, Kaori,Okumura, Miho,Nagaya, Shigeo

, p. 2026 - 2028 (2013/04/23)

A new HWE reagent, (o-tBuC6H4O)2P(O)CH2CN (2e), reacts with various types of aldehydes to give Z-a,bunsaturated nitriles with 86% to >99% Z-selectivity. Especially, the reaction of 2e with bulkier aldehydes, both aromatic and aliphatic, gave the Z-olefins with extremely high selectivity. The combination of t-BuOK and 18-crown-6 (1 equiv) is the base of choice for aromatic aldehydes and t-BuOK is generally the base of choice for aliphatic aldehydes.
