93716-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93716-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,1 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93716-69:
(7*9)+(6*3)+(5*7)+(4*1)+(3*6)+(2*6)+(1*9)=159
159 % 10 = 9
So 93716-69-9 is a valid CAS Registry Number.
