63674-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63674-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,6,7 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 63674-17:
(7*6)+(6*3)+(5*6)+(4*7)+(3*4)+(2*1)+(1*7)=139
139 % 10 = 9
So 63674-17-9 is a valid CAS Registry Number.
