1373257-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1373257-70-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,2,5 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1373257-70:
(9*1)+(8*3)+(7*7)+(6*3)+(5*2)+(4*5)+(3*7)+(2*7)+(1*0)=165
165 % 10 = 5
So 1373257-70-5 is a valid CAS Registry Number.
