Check Digit Verification of cas no
The CAS Registry Mumber 631912-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,1,9,1 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 631912-19:
(8*6)+(7*3)+(6*1)+(5*9)+(4*1)+(3*2)+(2*1)+(1*9)=141
141 % 10 = 1
So 631912-19-1 is a valid CAS Registry Number.
