198225-21-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 198225-21-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,2,2 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 198225-21:
(8*1)+(7*9)+(6*8)+(5*2)+(4*2)+(3*5)+(2*2)+(1*1)=157
157 % 10 = 7
So 198225-21-7 is a valid CAS Registry Number.
