Check Digit Verification of cas no
The CAS Registry Mumber 1347750-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,7,7,5 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1347750-72:
(9*1)+(8*3)+(7*4)+(6*7)+(5*7)+(4*5)+(3*0)+(2*7)+(1*2)=174
174 % 10 = 4
So 1347750-72-4 is a valid CAS Registry Number.
