198769-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 198769-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,7,6 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 198769-12:
(8*1)+(7*9)+(6*8)+(5*7)+(4*6)+(3*9)+(2*1)+(1*2)=209
209 % 10 = 9
So 198769-12-9 is a valid CAS Registry Number.
