Check Digit Verification of cas no
The CAS Registry Mumber 663957-56-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,3,9,5 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 663957-56:
(8*6)+(7*6)+(6*3)+(5*9)+(4*5)+(3*7)+(2*5)+(1*6)=210
210 % 10 = 0
So 663957-56-0 is a valid CAS Registry Number.
