Check Digit Verification of cas no

The CAS Registry Mumber 1255772-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,5,7,7 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1255772-40:
(9*1)+(8*2)+(7*5)+(6*5)+(5*7)+(4*7)+(3*2)+(2*4)+(1*0)=167
167 % 10 = 7
So 1255772-40-7 is a valid CAS Registry Number.

Biomimetic asymmetric hydrogenation: In situ regenerable Hantzsch esters for asymmetric hydrogenation of benzoxazinones

Chen, Qing-An,Chen, Mu-Wang,Yu, Chang-Bin,Shi, Lei,Wang, Duo-Sheng,Yang, Yan,Zhou, Yong-Gui

, p. 16432 - 16435 (2011)

A catalytic amount of Hantzsch ester that could be regenerated in situ by Ru complexes under hydrogen gas has been employed in the biomimetic asymmetric hydrogenation of benzoxazinones with up to 99% ee in the presence of chiral phosphoric acid. The use of hydrogen gas as a reductant for the regeneration of Hantzsch esters makes this hydrogenation an ideal atom economic process.
