1234064-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1234064-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,0,6 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1234064-57:
(9*1)+(8*2)+(7*3)+(6*4)+(5*0)+(4*6)+(3*4)+(2*5)+(1*7)=123
123 % 10 = 3
So 1234064-57-3 is a valid CAS Registry Number.
