99261-03-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99261-03-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,6 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99261-03:
(7*9)+(6*9)+(5*2)+(4*6)+(3*1)+(2*0)+(1*3)=157
157 % 10 = 7
So 99261-03-7 is a valid CAS Registry Number.
