Check Digit Verification of cas no
The CAS Registry Mumber 12750-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,5 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12750-99:
(7*1)+(6*2)+(5*7)+(4*5)+(3*0)+(2*9)+(1*9)=101
101 % 10 = 1
So 12750-99-1 is a valid CAS Registry Number.
