1241493-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1241493-92-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,4,9 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1241493-92:
(9*1)+(8*2)+(7*4)+(6*1)+(5*4)+(4*9)+(3*3)+(2*9)+(1*2)=144
144 % 10 = 4
So 1241493-92-4 is a valid CAS Registry Number.
