877603-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 877603-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,6,0 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 877603-63:
(8*8)+(7*7)+(6*7)+(5*6)+(4*0)+(3*3)+(2*6)+(1*3)=209
209 % 10 = 9
So 877603-63-9 is a valid CAS Registry Number.
