Check Digit Verification of cas no

The CAS Registry Mumber 97678-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,7 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97678-21:
(7*9)+(6*7)+(5*6)+(4*7)+(3*8)+(2*2)+(1*1)=192
192 % 10 = 2
So 97678-21-2 is a valid CAS Registry Number.
