312269-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 312269-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,2,6 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 312269-76:
(8*3)+(7*1)+(6*2)+(5*2)+(4*6)+(3*9)+(2*7)+(1*6)=124
124 % 10 = 4
So 312269-76-4 is a valid CAS Registry Number.
