79918-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79918-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,1 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 79918-22:
(7*7)+(6*9)+(5*9)+(4*1)+(3*8)+(2*2)+(1*2)=182
182 % 10 = 2
So 79918-22-2 is a valid CAS Registry Number.
