312529-71-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 312529-71-8 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 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 312529-71:
(8*3)+(7*1)+(6*2)+(5*5)+(4*2)+(3*9)+(2*7)+(1*1)=118
118 % 10 = 8
So 312529-71-8 is a valid CAS Registry Number.
