91229-98-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91229-98-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,2 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91229-98:
(7*9)+(6*1)+(5*2)+(4*2)+(3*9)+(2*9)+(1*8)=140
140 % 10 = 0
So 91229-98-0 is a valid CAS Registry Number.
