943734-04-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 943734-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,3,7,3 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 943734-04:
(8*9)+(7*4)+(6*3)+(5*7)+(4*3)+(3*4)+(2*0)+(1*4)=181
181 % 10 = 1
So 943734-04-1 is a valid CAS Registry Number.
