Check Digit Verification of cas no

The CAS Registry Mumber 70851-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,5 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70851-34:
(7*7)+(6*0)+(5*8)+(4*5)+(3*1)+(2*3)+(1*4)=122
122 % 10 = 2
So 70851-34-2 is a valid CAS Registry Number.
