Check Digit Verification of cas no
The CAS Registry Mumber 41891-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,9 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 41891-38:
(7*4)+(6*1)+(5*8)+(4*9)+(3*1)+(2*3)+(1*8)=127
127 % 10 = 7
So 41891-38-7 is a valid CAS Registry Number.
