312514-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 312514-97-9 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 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 312514-97:
(8*3)+(7*1)+(6*2)+(5*5)+(4*1)+(3*4)+(2*9)+(1*7)=109
109 % 10 = 9
So 312514-97-9 is a valid CAS Registry Number.
