253776-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 253776-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,7,7 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 253776-40:
(8*2)+(7*5)+(6*3)+(5*7)+(4*7)+(3*6)+(2*4)+(1*0)=158
158 % 10 = 8
So 253776-40-8 is a valid CAS Registry Number.
