91022-31-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91022-31-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,2 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91022-31:
(7*9)+(6*1)+(5*0)+(4*2)+(3*2)+(2*3)+(1*1)=90
90 % 10 = 0
So 91022-31-0 is a valid CAS Registry Number.
