Check Digit Verification of cas no
The CAS Registry Mumber 201995-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,9,9 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 201995-63:
(8*2)+(7*0)+(6*1)+(5*9)+(4*9)+(3*5)+(2*6)+(1*3)=133
133 % 10 = 3
So 201995-63-3 is a valid CAS Registry Number.
