Check Digit Verification of cas no
The CAS Registry Mumber 15749-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,4 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15749-44:
(7*1)+(6*5)+(5*7)+(4*4)+(3*9)+(2*4)+(1*4)=127
127 % 10 = 7
So 15749-44-7 is a valid CAS Registry Number.
