Check Digit Verification of cas no

The CAS Registry Mumber 5642-33-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,4 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5642-33:
(6*5)+(5*6)+(4*4)+(3*2)+(2*3)+(1*3)=91
91 % 10 = 1
So 5642-33-1 is a valid CAS Registry Number.
