312522-79-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 312522-79-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,5,2 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 312522-79:
(8*3)+(7*1)+(6*2)+(5*5)+(4*2)+(3*2)+(2*7)+(1*9)=105
105 % 10 = 5
So 312522-79-5 is a valid CAS Registry Number.
