Check Digit Verification of cas no

The CAS Registry Mumber 179996-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,9,9 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 179996-99:
(8*1)+(7*7)+(6*9)+(5*9)+(4*9)+(3*6)+(2*9)+(1*9)=237
237 % 10 = 7
So 179996-99-7 is a valid CAS Registry Number.

A catalytic amount of titanium tetrahalide as promoter for the addition reaction of silyl ketene acetals to imines

Shimizu, Makoto,Kume, Kouji,Fujisawa, Tamotsu

, p. 545 - 546 (1996)

In the presence of a catalytic amount of TiBr4 or Til4, the reaction of silyl ketene acetals with imines smoothly proceeds to give the corresponding β-amino esters in high yield with high anti-selectivity.
