634613-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 634613-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,6,1 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 634613-77:
(8*6)+(7*3)+(6*4)+(5*6)+(4*1)+(3*3)+(2*7)+(1*7)=157
157 % 10 = 7
So 634613-77-7 is a valid CAS Registry Number.
