87634-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87634-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,3 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87634-07:
(7*8)+(6*7)+(5*6)+(4*3)+(3*4)+(2*0)+(1*7)=159
159 % 10 = 9
So 87634-07-9 is a valid CAS Registry Number.
