Check Digit Verification of cas no

The CAS Registry Mumber 211997-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,9,9 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 211997-74:
(8*2)+(7*1)+(6*1)+(5*9)+(4*9)+(3*7)+(2*7)+(1*4)=149
149 % 10 = 9
So 211997-74-9 is a valid CAS Registry Number.

Asymmetric synthesis of the mC7N core of the manumycin family: Preparation of (+)-MT 35214 and a formal total synthesis of (-)-alisamycin

Macdonald, Gregor,Alcaraz, Lilian,Lewis, Norman J.,Taylor, Richard J. K.

, p. 5433 - 5436 (1998)

An asymmetric approach to the mC7N epoxyquinone central unit of the manumycin antibiotics is described based on the enantioselective (89% ee) chiral phase transfer epoxidation of a substituted cyclohexenone. The chiral epoxide is employed in the trust syntheses of the title compounds in enantiomerically pure form.
