79221-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79221-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,2 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79221-18:
(7*7)+(6*9)+(5*2)+(4*2)+(3*1)+(2*1)+(1*8)=134
134 % 10 = 4
So 79221-18-4 is a valid CAS Registry Number.
