Check Digit Verification of cas no

The CAS Registry Mumber 88068-13-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,0,6 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 88068-13:
(7*8)+(6*8)+(5*0)+(4*6)+(3*8)+(2*1)+(1*3)=157
157 % 10 = 7
So 88068-13-7 is a valid CAS Registry Number.

SIMPLE AND CHEMOSELECTIVE SYNTHESIS OF KETONES FROM CARBOXYLIC ACIDS AND GRIGNARD REAGENTS USING DICHLOROTRIPHENYLPHOSPHORANE

Fujisawa, Tamotsu,Iida, Sachio,Uehara, Hiroshi,Sato, Toshio

, p. 1267 - 1270 (1983)

Dichlorotriphenylphosphorane was found to be a good condensation reagent for synthesis of ketones from carboxylic acids and Grignard reagents under mild conditions.Synthetic utility of the present method is demonstrated by the chemoselective reaction of carboxylic acids possessing such a functional group as halogen, cyano, or carbonyl.
