Check Digit Verification of cas no

The CAS Registry Mumber 1215859-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,5,8,5 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1215859-40:
(9*1)+(8*2)+(7*1)+(6*5)+(5*8)+(4*5)+(3*9)+(2*4)+(1*0)=157
157 % 10 = 7
So 1215859-40-7 is a valid CAS Registry Number.
