393516-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 393516-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,3,5,1 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 393516-55:
(8*3)+(7*9)+(6*3)+(5*5)+(4*1)+(3*6)+(2*5)+(1*5)=167
167 % 10 = 7
So 393516-55-7 is a valid CAS Registry Number.
