Check Digit Verification of cas no

The CAS Registry Mumber 256454-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,4,5 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 256454-47:
(8*2)+(7*5)+(6*6)+(5*4)+(4*5)+(3*4)+(2*4)+(1*7)=154
154 % 10 = 4
So 256454-47-4 is a valid CAS Registry Number.

The first general, highly enantioselective lewis base organocatalyzed hydrosilylation of benzoxazinones and quinoxalinones

Xue, Zhou-Yang,Jiang, Yan,Peng, Xiao-Zhi,Yuan, Wei-Cheng,Zhang, Xiao-Mei

supporting information; experimental part, p. 2132 - 2136 (2010/11/04)

The first general, highly enantioselective hydrosilylation of benzoxazinones and quinoxalinones has been developed. The chiral Lewis base organocatalysis that are readily accessible from (1S,2R)-ephedrine and (1R,2S)-ephedrine promoted the title reaction to afford various chiral dihydrobenzoxazinones and dihydroquinoxalinones with good yields as well as good enantioselectivities.
