744221-74-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 744221-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,4,2,2 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 744221-74:
(8*7)+(7*4)+(6*4)+(5*2)+(4*2)+(3*1)+(2*7)+(1*4)=147
147 % 10 = 7
So 744221-74-7 is a valid CAS Registry Number.
