1252785-23-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1252785-23-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,7,8 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1252785-23:
(9*1)+(8*2)+(7*5)+(6*2)+(5*7)+(4*8)+(3*5)+(2*2)+(1*3)=161
161 % 10 = 1
So 1252785-23-1 is a valid CAS Registry Number.
