Check Digit Verification of cas no
The CAS Registry Mumber 66621-35-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,2 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.Calculate Digit Verification of CAS Registry Number 66621-35:
(7*6)+(6*6)+(5*6)+(4*2)+(3*1)+(2*3)+(1*5)=130
130 % 10 = 0
So 66621-35-0 is a valid CAS Registry Number.
