133157-70-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133157-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,1,5 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133157-70:
(8*1)+(7*3)+(6*3)+(5*1)+(4*5)+(3*7)+(2*7)+(1*0)=107
107 % 10 = 7
So 133157-70-7 is a valid CAS Registry Number.
