1001091-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1001091-83-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,1,0,9 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1001091-83:
(9*1)+(8*0)+(7*0)+(6*1)+(5*0)+(4*9)+(3*1)+(2*8)+(1*3)=73
73 % 10 = 3
So 1001091-83-3 is a valid CAS Registry Number.
