137512-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137512-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,1 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137512-91:
(8*1)+(7*3)+(6*7)+(5*5)+(4*1)+(3*2)+(2*9)+(1*1)=125
125 % 10 = 5
So 137512-91-5 is a valid CAS Registry Number.
