1277098-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1277098-69-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,7,0,9 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1277098-69:
(9*1)+(8*2)+(7*7)+(6*7)+(5*0)+(4*9)+(3*8)+(2*6)+(1*9)=197
197 % 10 = 7
So 1277098-69-7 is a valid CAS Registry Number.
