1421767-88-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421767-88-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,7,6 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1421767-88:
(9*1)+(8*4)+(7*2)+(6*1)+(5*7)+(4*6)+(3*7)+(2*8)+(1*8)=165
165 % 10 = 5
So 1421767-88-5 is a valid CAS Registry Number.
