63517-98-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63517-98-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,1 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 63517-98:
(7*6)+(6*3)+(5*5)+(4*1)+(3*7)+(2*9)+(1*8)=136
136 % 10 = 6
So 63517-98-6 is a valid CAS Registry Number.
