1421739-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421739-65-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,7,3 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1421739-65:
(9*1)+(8*4)+(7*2)+(6*1)+(5*7)+(4*3)+(3*9)+(2*6)+(1*5)=152
152 % 10 = 2
So 1421739-65-2 is a valid CAS Registry Number.
