1253976-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1253976-99-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,9,7 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1253976-99:
(9*1)+(8*2)+(7*5)+(6*3)+(5*9)+(4*7)+(3*6)+(2*9)+(1*9)=196
196 % 10 = 6
So 1253976-99-6 is a valid CAS Registry Number.
