126717-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126717-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,1 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126717-63:
(8*1)+(7*2)+(6*6)+(5*7)+(4*1)+(3*7)+(2*6)+(1*3)=133
133 % 10 = 3
So 126717-63-3 is a valid CAS Registry Number.
