1253853-75-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1253853-75-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,8,5 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1253853-75:
(9*1)+(8*2)+(7*5)+(6*3)+(5*8)+(4*5)+(3*3)+(2*7)+(1*5)=166
166 % 10 = 6
So 1253853-75-6 is a valid CAS Registry Number.
