91003-74-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91003-74-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,0 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91003-74:
(7*9)+(6*1)+(5*0)+(4*0)+(3*3)+(2*7)+(1*4)=96
96 % 10 = 6
So 91003-74-6 is a valid CAS Registry Number.
