Check Digit Verification of cas no

The CAS Registry Mumber 85706-52-1 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 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85706-52:
(7*8)+(6*5)+(5*7)+(4*0)+(3*6)+(2*5)+(1*2)=151
151 % 10 = 1
So 85706-52-1 is a valid CAS Registry Number.
