916768-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 916768-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,7,6 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 916768-39:
(8*9)+(7*1)+(6*6)+(5*7)+(4*6)+(3*8)+(2*3)+(1*9)=213
213 % 10 = 3
So 916768-39-3 is a valid CAS Registry Number.
