98753-27-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98753-27-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,5 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 98753-27:
(7*9)+(6*8)+(5*7)+(4*5)+(3*3)+(2*2)+(1*7)=186
186 % 10 = 6
So 98753-27-6 is a valid CAS Registry Number.
