Check Digit Verification of cas no

The CAS Registry Mumber 332902-42-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,9,0 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 332902-42:
(8*3)+(7*3)+(6*2)+(5*9)+(4*0)+(3*2)+(2*4)+(1*2)=118
118 % 10 = 8
So 332902-42-8 is a valid CAS Registry Number.

, p. 615 - 617 (2001)

(Matrix presented) High stereoselectivities (up to 98% de) have been achieved for the Lewis acid-mediated cross-coupling reaction of dimethyl acetals to a chiral 1,3-thiazolidine-2-thione-derived titanium enolate. The reaction affords enantiopure anti α-m
