312510-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 312510-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,5,1 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 312510-13:
(8*3)+(7*1)+(6*2)+(5*5)+(4*1)+(3*0)+(2*1)+(1*3)=77
77 % 10 = 7
So 312510-13-7 is a valid CAS Registry Number.
