442639-30-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 442639-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,2,6,3 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 442639-30:
(8*4)+(7*4)+(6*2)+(5*6)+(4*3)+(3*9)+(2*3)+(1*0)=147
147 % 10 = 7
So 442639-30-7 is a valid CAS Registry Number.
