Check Digit Verification of cas no

The CAS Registry Mumber 169872-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,8,7 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 169872-81:
(8*1)+(7*6)+(6*9)+(5*8)+(4*7)+(3*2)+(2*8)+(1*1)=195
195 % 10 = 5
So 169872-81-5 is a valid CAS Registry Number.

Johnson,Nerurkar,Golebiowski,Sundram,Esker

, p. 1139 - 1140 (2007/10/02)

(4R,5S)-trans-4,5-Bis(tert-butyldimethylsilyloxy)cyclopent-2-enone 8 and (4R,5S)-trans-4,5-di(benzyloxy)cyclopent-2-enone 20 are prepared by equilibration of the corresponding cis derivatives; enone 8 is transformed into the glucosidase inhibitor, D-1-deoxynojirimycin 14.
