136271-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136271-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,2,7 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136271-13:
(8*1)+(7*3)+(6*6)+(5*2)+(4*7)+(3*1)+(2*1)+(1*3)=111
111 % 10 = 1
So 136271-13-1 is a valid CAS Registry Number.
