791637-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 791637-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,1,6,3 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 791637-64:
(8*7)+(7*9)+(6*1)+(5*6)+(4*3)+(3*7)+(2*6)+(1*4)=204
204 % 10 = 4
So 791637-64-4 is a valid CAS Registry Number.
