Check Digit Verification of cas no
The CAS Registry Mumber 63820-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,2 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 63820-35:
(7*6)+(6*3)+(5*8)+(4*2)+(3*0)+(2*3)+(1*5)=119
119 % 10 = 9
So 63820-35-9 is a valid CAS Registry Number.
