100971-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100971-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,7 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100971-13:
(8*1)+(7*0)+(6*0)+(5*9)+(4*7)+(3*1)+(2*1)+(1*3)=89
89 % 10 = 9
So 100971-13-9 is a valid CAS Registry Number.
