1421136-07-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421136-07-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,1,3 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1421136-07:
(9*1)+(8*4)+(7*2)+(6*1)+(5*1)+(4*3)+(3*6)+(2*0)+(1*7)=103
103 % 10 = 3
So 1421136-07-3 is a valid CAS Registry Number.
