Check Digit Verification of cas no
The CAS Registry Mumber 130850-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,5 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130850-63:
(8*1)+(7*3)+(6*0)+(5*8)+(4*5)+(3*0)+(2*6)+(1*3)=104
104 % 10 = 4
So 130850-63-4 is a valid CAS Registry Number.
