Check Digit Verification of cas no

The CAS Registry Mumber 836643-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,6,6,4 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 836643-56:
(8*8)+(7*3)+(6*6)+(5*6)+(4*4)+(3*3)+(2*5)+(1*6)=192
192 % 10 = 2
So 836643-56-2 is a valid CAS Registry Number.
