Check Digit Verification of cas no

The CAS Registry Mumber 1170680-42-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,0,6,8 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1170680-42:
(9*1)+(8*1)+(7*7)+(6*0)+(5*6)+(4*8)+(3*0)+(2*4)+(1*2)=138
138 % 10 = 8
So 1170680-42-8 is a valid CAS Registry Number.

Catalytic asymmetric epoxidation of alkenes with arabinose-derived ketones containing a cyclohexane-1,2-diacetal

Shing, Tony K.M.,Luk, To

experimental part, p. 883 - 886 (2009/09/08)

The effect of diol blocking groups, cyclohexane-1,2-diacetal verses butane-1,2-diacetal, on the asymmetric epoxidation of trans- and cis-alkenes by arabinose-derived ketones is reported. The ketone catalysts with a cyclohexane-1,2-acetal display similar asymmetric induction as those catalysts with a butane-1,2-diacetal in most cases. For (E)-1-benzyloxy-4-hexene, the ee of the enantioselective epoxidation has reached 61% with the cyclohexane-1,2-dineopentyl acetal ketone catalyst.
