133272-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133272-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,7 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133272-22:
(8*1)+(7*3)+(6*3)+(5*2)+(4*7)+(3*2)+(2*2)+(1*2)=97
97 % 10 = 7
So 133272-22-7 is a valid CAS Registry Number.
