149741-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149741-61-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,7,4 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 149741-61:
(8*1)+(7*4)+(6*9)+(5*7)+(4*4)+(3*1)+(2*6)+(1*1)=157
157 % 10 = 7
So 149741-61-7 is a valid CAS Registry Number.
