123746-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123746-57-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,4 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123746-57:
(8*1)+(7*2)+(6*3)+(5*7)+(4*4)+(3*6)+(2*5)+(1*7)=126
126 % 10 = 6
So 123746-57-6 is a valid CAS Registry Number.
