31336-25-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31336-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,3 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31336-25:
(7*3)+(6*1)+(5*3)+(4*3)+(3*6)+(2*2)+(1*5)=81
81 % 10 = 1
So 31336-25-1 is a valid CAS Registry Number.
