100157-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100157-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,5 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 100157-26:
(8*1)+(7*0)+(6*0)+(5*1)+(4*5)+(3*7)+(2*2)+(1*6)=64
64 % 10 = 4
So 100157-26-4 is a valid CAS Registry Number.
