76983-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76983-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,8 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 76983-16:
(7*7)+(6*6)+(5*9)+(4*8)+(3*3)+(2*1)+(1*6)=179
179 % 10 = 9
So 76983-16-9 is a valid CAS Registry Number.
