1421961-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421961-54-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,9,6 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1421961-54:
(9*1)+(8*4)+(7*2)+(6*1)+(5*9)+(4*6)+(3*1)+(2*5)+(1*4)=147
147 % 10 = 7
So 1421961-54-7 is a valid CAS Registry Number.
