1425864-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1425864-77-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,5,8,6 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1425864-77:
(9*1)+(8*4)+(7*2)+(6*5)+(5*8)+(4*6)+(3*4)+(2*7)+(1*7)=182
182 % 10 = 2
So 1425864-77-2 is a valid CAS Registry Number.
