63539-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63539-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,3 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 63539-61:
(7*6)+(6*3)+(5*5)+(4*3)+(3*9)+(2*6)+(1*1)=137
137 % 10 = 7
So 63539-61-7 is a valid CAS Registry Number.
