252763-81-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252763-81-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,7,6 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 252763-81:
(8*2)+(7*5)+(6*2)+(5*7)+(4*6)+(3*3)+(2*8)+(1*1)=148
148 % 10 = 8
So 252763-81-8 is a valid CAS Registry Number.
