1272542-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1272542-13-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,2,5,4 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1272542-13:
(9*1)+(8*2)+(7*7)+(6*2)+(5*5)+(4*4)+(3*2)+(2*1)+(1*3)=138
138 % 10 = 8
So 1272542-13-8 is a valid CAS Registry Number.
