312515-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 312515-22-3 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 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 312515-22:
(8*3)+(7*1)+(6*2)+(5*5)+(4*1)+(3*5)+(2*2)+(1*2)=93
93 % 10 = 3
So 312515-22-3 is a valid CAS Registry Number.
