16983-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16983-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,8 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 16983-75:
(7*1)+(6*6)+(5*9)+(4*8)+(3*3)+(2*7)+(1*5)=148
148 % 10 = 8
So 16983-75-8 is a valid CAS Registry Number.
