Check Digit Verification of cas no

The CAS Registry Mumber 952251-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,2,2,5 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 952251-86:
(8*9)+(7*5)+(6*2)+(5*2)+(4*5)+(3*1)+(2*8)+(1*6)=174
174 % 10 = 4
So 952251-86-4 is a valid CAS Registry Number.

, p. 7352 - 7358 (2008/02/12)

(Chemical Equation Presented) A concise route toward the syntheses of (-)-drupacine and (+)- and (-)-cephalotaxine has been developed. The syntheses rely on Pd(II)-catalyzed aerobic oxidative heterocyclization chemistry, which was employed to rapidly cons
