63140-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63140-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,1,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 63140-90:
(7*6)+(6*3)+(5*1)+(4*4)+(3*0)+(2*9)+(1*0)=99
99 % 10 = 9
So 63140-90-9 is a valid CAS Registry Number.
