1257230-37-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1257230-37-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,2,3 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1257230-37:
(9*1)+(8*2)+(7*5)+(6*7)+(5*2)+(4*3)+(3*0)+(2*3)+(1*7)=137
137 % 10 = 7
So 1257230-37-7 is a valid CAS Registry Number.
