74630-95-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74630-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,3 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.Calculate Digit Verification of CAS Registry Number 74630-95:
(7*7)+(6*4)+(5*6)+(4*3)+(3*0)+(2*9)+(1*5)=138
138 % 10 = 8
So 74630-95-8 is a valid CAS Registry Number.
