Check Digit Verification of cas no
The CAS Registry Mumber 66773-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,7,7 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66773-31:
(7*6)+(6*6)+(5*7)+(4*7)+(3*3)+(2*3)+(1*1)=157
157 % 10 = 7
So 66773-31-7 is a valid CAS Registry Number.
