Check Digit Verification of cas no
The CAS Registry Mumber 1322749-72-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,2,7,4 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1322749-72:
(9*1)+(8*3)+(7*2)+(6*2)+(5*7)+(4*4)+(3*9)+(2*7)+(1*2)=153
153 % 10 = 3
So 1322749-72-3 is a valid CAS Registry Number.
