474970-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 474970-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,9,7 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 474970-91:
(8*4)+(7*7)+(6*4)+(5*9)+(4*7)+(3*0)+(2*9)+(1*1)=197
197 % 10 = 7
So 474970-91-7 is a valid CAS Registry Number.
