198962-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 198962-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,9,6 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 198962-91:
(8*1)+(7*9)+(6*8)+(5*9)+(4*6)+(3*2)+(2*9)+(1*1)=213
213 % 10 = 3
So 198962-91-3 is a valid CAS Registry Number.
