1285712-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1285712-83-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,5,7,1 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1285712-83:
(9*1)+(8*2)+(7*8)+(6*5)+(5*7)+(4*1)+(3*2)+(2*8)+(1*3)=175
175 % 10 = 5
So 1285712-83-5 is a valid CAS Registry Number.
