75136-29-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75136-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,1,3 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75136-29:
(7*7)+(6*5)+(5*1)+(4*3)+(3*6)+(2*2)+(1*9)=127
127 % 10 = 7
So 75136-29-7 is a valid CAS Registry Number.
