61313-39-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61313-39-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,3,1 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 61313-39:
(7*6)+(6*1)+(5*3)+(4*1)+(3*3)+(2*3)+(1*9)=91
91 % 10 = 1
So 61313-39-1 is a valid CAS Registry Number.
