Check Digit Verification of cas no

The CAS Registry Mumber 85707-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,0 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 85707-11:
(7*8)+(6*5)+(5*7)+(4*0)+(3*7)+(2*1)+(1*1)=145
145 % 10 = 5
So 85707-11-5 is a valid CAS Registry Number.

STREOSELECTIVE REDUCTION OF THE STEROIDAL 23-EN-22-ONE: A ROUTE TO THE SIDE CHAIN OF THE PLANT GROWTH PROMOTER BRASSINOLIDE.

Takahashi, Takashi,Ootake, Atsushi,Yamada, Haruo,Tsuji, Jiro

, p. 69 - 72 (1985)

The side chain of brassinolide (1) was streoselectively synthesized, in which the 20(S)- and the 22(R)-configurations were introduced by the alkylation (SN2) of the 20(R)-tosyloxy steroid 7 with the protected cyanohydrin 8 followed by the streo
